METHOD FOR SELF-TESTING NOTIFICATION APPLIANCES IN ALARM SYSTEMS |
摘要 |
<p>Method for self-testing notification appliances in an alarm system, including the steps of measuring ambient noise at a notification appliance, comparing the measured ambient noise to a threshold ambient noise level, and performing a self-test of the notification appliance if the measured ambient noise does not exceed the threshold ambient noise level. Method may further include the step of recording a fail result for the notification appliance if the measured ambient noise exceeds the threshold ambient noise level. Performing the self-test of the notification appliance may include the steps of activating a notification feature of the notification appliance, measuring output of the notification feature, comparing the measured output to a predefined value, recording a pass result for the notification appliance if the measured output exceeds the predefined value, and recording a fail result for the notification appliance if the measured output does not exceed the predefined value.</p> |
